A successful treatment of malocclusions often depends on appropriate orthopedic intervention to correct underlying skeletal discrepancies. The ability to predict the magnitude and direction of a patients facial growth early in life would enable the clinician to identify those who required interceptive growth identification and to ensure that the appropriate treatment can be rendered while growth is possible, and to forego unnecessary treatment on patients with skeletal discrepancies whose growth pattern would probably lead to correction without orthopedic intervention (Kolodziej et al, 2002)....
